Application led September 20, 1909. Serial No. 518,551.

To all whom it may concern:

Be it known that I, WALTER E. Po'r'rs, a citizen of the United States,residing at Santa Fe, in the county of Maury, State of Tennessee, haveinvented certain new and useful Improvements in Automatic Wagon-Loaders; and I do herebydeclare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to wagon loaders and has special reference to anautomatic loader wherein a draft animal is employed both for the purposeof hoisting and for overhauling the fall prior to a second hoist.

Briefly stated the invention consists of a suitable derrick, an inclinedplatform located below the derrick, a scoop, a runner movably attachedto the rear end of said scoop, a ground stake properly positioned fromthe derrick and platform, and a rope one end of which is attached to thederrick and passing over a suitable block attached to the scoop, theground stake and. scoop, the opposite end of said rope having its endsecured to said derrick below the block thereon, the ground stake beingso positioned in respect to the platform as to-caus'e the receiving endof the scoop to advance on a line with one corner of said platform,whereby the load carried by the scoop is readily elevated and depositedfrom the opposite upper corner of the platform.

The invention has for its object to provide a device of this kind soarranged that the ordinary hand method of overhauling the hoisting fallcommon in such devices will be eliminated. y l

- Vith the above and other objects in view the invention consists ingenera-l ofthe combination with a material holding means, of a hoistingfall attached to said means and having its free end also secured to saidmeans, and other means for attaching a draft animal secured to therunning part of said fall so that the animal can pull the materialholding means in either direction.

The invention further consists in certain novel details of constructionand combinations of parts hereinafter fully described, illustrated intheaccompanying drawings, and specifically set forth in the claim.

In the accompanying drawings, like characters of reference indicate likeparts inthe several views, and Figure 1 is a side elevation of ahoisting device constructed in accordance with this invention. Fig. 2 isa top plan view thereof. Fig. 3 shows a modified formY of materialholding means. Fig. l shows a second modified form of material holdingmeans.

The frame for this hoist consists of a front timber 10 and lateral orrear timbers 11 which are bolted together at the top by means of a bolt12 and have the bottoms of the legs spread apart so that there is formeda species of tripod.

At 18 is an eye bolt which passes through the front timber 10 and issecured thereto by means of. a suitable nut. At 14 is a similar eye boltwhereto is secured Va single sheave block 15. v

In the form of material holder shown in I*1 ig. 1 there is provided theordinary scoop 16 having` a bail 17 and hooked to this bail is a singlesheave block 18. Suitably positioned at some distance from the tripod isa ground stake 19 whereto is secured a single sheave block 20. A ropeextends from` the eye bolt 13 through the block 18, thence ythrough theVblock 15 and thence through the block 20 and the free end of this ropeis connected to the hoisting means as indicated at 21. For the purposeof distinguishing the various parts of this rope during the descriptionthe portion extending from the eye bolt 13 to the block 18 will be knownas the standing part while the portion between the attachment of the endat 21 and the block 20 will be known as the running part. Attached tothe running part of therope in spaced relation to the material holdingmeans is a swingletree 22. It is found advisable that the distance fromthe point 21 to the swingletree shall be equal to the extreme distancewhich it is required to move the scoop 16 and to this end the groundstake 19 should be positioned at least twice the distance from thecenter of the tripod that is required for the extreme movement of thescoop 16. The reason for this will be obvious when it is considered thatthe draft animal must move two feet for every foot of movement of thescoop since the hoisting fall thus constructed is what is known as asingle fall. In order to run the material up into a wagon vit ispreferred that there shall be a trestle 23 positioned beneath the tripodand on ioo this trestle is supported one end of an inclined frame 24 upwhich the scoop may ass. p In the forms of material holding devicesshown in Fig. 3 and Fig. 4 there is provided in the first instanceadevice for grasping such material as ice and comprising a pair of tongs25 While in the latter instance there is provided a pair of logginghooks 26 connected by the usual chain 27 for the purpose of moving logsand other heavy timbers. It is obvious that without disturbing thearrangement ofthe hoisting fall the hooks or the tongs could readily besubstituted for the scoop 16 and the operation remain the same.

In theoperation of this device let it be supposed that it is desired tomove material from a point sixty feet distant from the center of thetripod to the center of said tripod; In order to do this the groundstake 19 is positioned at least one-hundred andy twenty feet distant andthe swingletree or other draft device isattached sixty feet to the rearof the scoop 16. Now, the animal is driven Vforward in the direction ofthe tripod and as the animal walks the onehundred and twenty feet thatwill bring him I beneath the tripod the scoop will have moved sixty feetat the same time. Meanwhile the running part of the rope will haveslackened up between the scoop and the draft device so that slack equaltosixty feet will be left between the animal and the scoop when thelimit of forward travel of thle scoop is reached. The animal is thenturned around and driven backward. In the first sixty feet he has aperiod of rest but at the end of this time the rope between the scoopand the draft device becomes t-aut and during the next sixty feet thescoop will be pulled backward and overhaul the fall as the block 18 runsdown on the standing part of the rope. At the endof the next sixty feetof travel the animal will be in precisely his original place as willalso the scoop. By arranging the ground stake 19 in the position inrespect to the inclined platform 24 as clearly Copies of this patent maybe obtained for ve cents each, by addressing Washington, 13.10.

shown in Fig. 2 and previously referred to, the load carried by thescoop 16 is elevated to the upper corner of said platform where the loadcan be conveniently and readily deposited into the wagon from one sideof said platform. The. animal is again turned around and the operationrepeated, this being done as many times as may be necessary to load thewagon, the scoop passing up the incline and being dumped at the endthereof on each forward travel. It is obvious that logs might be hauledvup the incline or ice may be conveyed therealong in the same manner andit is also obvious that in order to increase the distance of the haul itis between the distances the material is to be moved and the distancebetween the center of the tripod and the ground stake 19.

There has t-hus been provided a simple and efficient device of the kindVdescribed and for the purpose specified. Y

Having thus described the invention, what is claimed as new, is Y Adeviceof the character described comprising a suitable derrick, a fixedinclined platform positioned within the latter with its lower receivingend extending beyond the derrick, a stake anchored at a suitabledistance from the derrick, a pulley attached to said anchor, a movablescoop having a pulley attached thereto, arunner, oneend of which isattached to the rear closed end of t-he latter, a draft appliance,comprising a rope, one end of which is attached to the WALTER n.L roTTs.
